Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II

DESIGN A BRACKET-II USING NX CAD (Sheet Metal):

OBJECTIVE:

• The aim of this project is to design the Bracket-II using NX CAD (Sheet Metal Application).

INTRODUCTION:

• NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned by Siemens PLM Software.
• NX sheet metal design software incorporates material and process information in sheet metal-specific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

DESIGN METHODOLOGY:

DESCRIPTION:

• NX CAD (Sheet Metal):
  • Open NX CAD sheet metal model.
    
• SET PREFERENCES:
  • Sets parameters and characterstics for Sheet Metal Commands.

• SKETCH:
  • Creates a sketch in the current application. Use the Direct Sketch tools to add curves, dimensions, constraints, etc.

• CONTOUR FLANGE:
  • Creates a base feature by extruding a sketch along a vector, or adds material by sweeping a sketch along an edge or chain of edges.
• NORMAL CUTOUT:
  • Cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

• BREAK CORNER:
  
  • Rounds or chamfers a sharp corner of a tab or flange.

• UNBEND:
  • Flattens a bend and the material adjacent to the bend.

• HOLE:
  • Adds a hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk, and threaded.

• ADVANCE FLANGE:
  • Adds a flange along an edge using a bend angle or a reference face. The edge and reference face can be curved.

• REBEND:
  • Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.

• GUSSET:
  • Creates a stiffening gusset on the part.

• DRAFTING:
  • Starts the Drafting application, which provides tools to create and maintain drawings of the design model.
    • New Sheet: Creates a new drawing sheet
    • Base View: Creates a model based view on the drawing sheet

CONCLUSION:

• Thus a Bracket-II is Design and Drafted by using NX CAD (Sheet Metal).

note:

the advanced flange option is not available in the student version of nx cad , so i have designed model with out advanced flange option
